FUNCTIONAL DESCRIPTION
REG1 Stand-by Regulator (Figure 5)
The stand-by regulator output voltage can be 5V or 3.3V. It is externally selectable by means of the ADJ pin:
- leaving the ADJ pin open, the output voltage is 5V;
- connecting the ADJ pin to the Vstby pin the output voltage becomes 3.3V.
This regulator is supplied by STCAP pin and provide the reset information.
It has a current protection which limits the maximum allowable output current.
Reset (Figure 6)
The RES pin is an open collector that is activated (that is forced to zero) when the stand-by regulator is not in
regulation (including thermal shutdown and faults). The indication that REG1 is in regulation is delayed by a time
